Vertex Pharmaceuticals Incorporated (NASDAQ:VRTX) today announced the U.S. Food and Drug Administration (FDA) has approved expanded use of ALYFTREK® (vanzacaftor/tezacaftor/ivacaftor) for the treatment of people with cystic fibrosis (CF) ages 6 and older with a variant in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that is either responsive based on clinical and/or in vitro data or results in production of CFTR protein. Additionally, the U.S. FDA has also expanded the indication statement for TRIKAFTA® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) in patients ages 2 and older.

This label expansion was supported by clinical and/or in vitro data from 564 variants demonstrating response to ALYFTREK and 521 variants demonstrating response to TRIKAFTA. As such, approximately 800 more people with a clinical diagnosis of CF in the U.S. are now eligible for a medicine that treats the underlying cause of their disease for the first time. This extension means approximately 95% of people with CF in the U.S. are now eligible for treatment with a CFTR modulator.

"This groundbreaking approval represents more than 20 years of innovation in CF, including testing over 600 variants in our laboratory, demonstrating clinical effects in large clinical trials, and studying younger people with CF so they can be treated as early as possible," said Carmen Bozic, M.D., Executive Vice President, Global Medicines Development and Medical Affairs, and Chief Medical Officer at Vertex. "With this label expansion, any variant that results in production of CFTR protein is now included in the ALYFTREK and TRIKAFTA labels, validating that these medicines can restore CFTR function and provide clinical benefit to patients regardless of where in the CFTR protein a variant is located. We thank the CF community and investigators for their trust and look forward to bringing ALYFTREK and TRIKAFTA to more patients than ever before."
